By which you mean that sendmail.cf contains the line:
DSrelay:mail.xyz.com ?
SMART_HOST will relay mail to destinations for which it doesn't have
explicit routing information.
Do you also have a mailertable defined which might include the
recipient domain, for example?

Try "sendmail -d60.5 -bv [user at example.com]" to see what might be
going on with local address parsing.
